COOLER MASTER XG850 Plus Platinum Power Supply Review

You are currently viewing COOLER MASTER XG850 Plus Platinum Power Supply Review

Among aficionados, Cooler Master is a well-known brand. The company first made PC cooling systems, but it quickly expanded into making cases and power supplies, which are largely to blame for its current fame. The company now produces hundreds of products and is well-known throughout the world, but they are constantly updating and improving their catalogs.

Despite expanding into gaming PC accessories and even related furniture, Cooler Master has maintained a strong focus on PC Cases, Coolers, and PSUs and offers a wide range of goods in each of these three categories. When this review was written, Cooler Master was selling a bizarre selection of over 75 PC cases, 90 coolers, and 120 PSUs.

We’re taking a look at Cooler Master, a well-known manufacturer of PC peripherals, new XG Plus Platinum series power supplies today. The RGB fan- and RGB display-equipped XG Plus Platinum is a unique PSU that was created to provide a high-quality PSU with a little more flare. The COOLER MASTER XG850 Plus Platinum Power Supply is the most potent member of the XG family, which includes models with 650 to 850 Watts of power.

COOLER MASTER XG850 Plus Platinum Power Supply Packaging

Cooler Master’s packaging design is everything from subtle in comparison to the majority of the current PC market. The lavish and bright artwork combines geometrical patterns with images and vivid hues. The machine must be transported in a very sturdy cardboard box and adequately wrapped in layers of wrapping foam.

Comparing Cooler Master’s packaging to the rest of the current PC market, it is clear that it is anything but subtle. Geometric patterns, images, and vibrant colors are all included into the extravagant and colorful artwork. The machine needs to be well wrapped in layers of packing foam and delivered in a very sturdy cardboard box.

All of the DC power cables, including the 24-pin ATX connector, can be removed from the XG Plus Platinum due to its modular construction. The cables are all naked, ribbon-like, and have black connections and wires throughout. No floppy connector or adapter is present.

COOLER MASTER XG850 Plus Platinum Power Supply Specs & Performance

With its 135mm fan and digital side panel, the COOLER MASTER XG850 Plus Platinum Power Supply is a completely modular 80 PLUS Platinum power supply with ARGB lighting. A 10-year warranty and top-tier performance are provided by the 100% Japanese capacitor construction of the XG Plus Platinum series. The PSU is compatible with Cooler Master’s MasterPlus+ software, which enables users to customize the RGB lighting of the fan and the information shown on the side panel. Users can also track information such as fan RPM, power supply temperature, and system power usage with this program.

Thanks to Active PFC, the XG850 PLUS Platinum runs at 100-240VAC without switching. More than 92% efficiency is the target for this power supply, which should be sufficient for up to 6x PCIe 6+2pin connectors for graphics cards. At Amazon, the Cooler Master XG850 costs $259.99 USD.

The COOLER MASTER XG850 Plus Platinum Power Supply chassis is 20 mm deeper than an ATX-compliant PSU, measuring 86 mm by 150 mm by 160 mm (H, W, D). The length of such a high-performance PSU is taken into account by the vast majority of modern PC cases, but the slightly longer length may still cause compatibility issues with some compact footprint designs.

Cooler Master chose a bespoke chassis with an embossed left side and an integrated fan finger protection because they genuinely want their newest PSU to stand out from the competition. If the device is positioned upside-down at the base of a conventional ATX chassis, the embossed left side will be visible. Most of the top side of the unit is covered by the sticker that lists its certifications and specs.

The 135 mm RGB fan that is installed within the XG Plus Platinum device has been rebranded by Cooler Master. The fan boasts a quiet and dependable hydro-dynamic sleeve bearing. Although it has a maximum speed of 1800 RPM, which is high for a fan of that size, the graphs provided on the box indicate that the fan shouldn’t even hit 1000 RPM in a typical environment.

Cooler Master claims that this PSU is entirely their own creation, and the interior of the XG Plus Platinum is unlike any platform we have seen before. However, Huizhou Xinhuiyuan Technology might dispute somewhat with that assertion. But we don’t know anything about the platform or how much the developers at Cooler Master contributed to its creation.

The Cooler Master XG Plus Platinum PSU’s filtering stage follows the rules exactly, using a total of four Y capacitors, two X capacitors, and two filtering inductors. There is a relay that can be used to avoid the NTC for more efficiency. On the primary side’s inverting components’ primary heatsink are the rectifying bridges. The unit’s side is covered by a separate heatsink to which the active APFC parts are fastened. The big 450V/680F APFC capacitor is supplied by Nippon Chemi-Con and is installed adjacent to a large filtering coil.

COOLER MASTER XG850 Plus Platinum Power Supply Conclusion

The COOLER MASTER XG850 Plus Platinum Power Supply electrical performance is respectable for a product in this price range and category, but it is in no way exceptional. Given that most manufacturers ignore the secondary 3.3 V and 5 V lines, the voltage regulation on all voltage lines is just under 1% across the nominal load range, which is quite good. The greatest ripple on the 12 V, 5 V, and 3.3 V lines, respectively, is 46 mV, 12 mV, and 10 mV, demonstrating the excellent power quality of all three voltage lines.

The COOLER MASTER XG850 Plus Platinum Power Supply is a grand slam. The XG850 is extremely effective and quiet while also having a sleek appearance. I adore the RGB panel, which can show system and power data in real time. I frequently wonder how much power my computer system uses from the wall, but the majority of monitoring solutions are cumbersome and/or difficult to read. Platinum efficiency is fantastic for lowering your electricity costs. Since Cooler Master shows an improvement of roughly 2%, I’ve often thought about running a 240V line for my PC merely to obtain a few% more. The XG850 is quite efficient; you don’t lose 90% efficiency until the system is operating at almost 90% of capacity, which is excellent.
